Description
[0001] The invention relates to a trigger diffuser intended to be
secured to the neck of a vial provided with an outlet valve. The
diffuser comprises fastening means for securing it to the vial,
actuation means for actuating the valve of the vial, a trigger
movable between a neutral position, in which the actuation means do
not actuate the valve, and a diffusion position, in which the
actuation means are moved in the direction of the valve so as to
actuate it, and an outlet channel for the transport out of the
diffuser of the product coming out of the valve when the latter is
actuated. In addition, the diffuser is provided with blocking means
movable between a blocking position, in which they block the
movement of the trigger so as to prevent it from reaching the
diffusion position, and a release position, in which the trigger
can be moved from the neutral position to the diffusion position.
The trigger is provided with a rib oriented toward the center of
the base and the blocking means are constituted by a vertical wall
pivotable between a blocking position and a release position.
[0002] Such diffusers are commonly used in the food and cosmetics
industries, in particular, for the diffusion of foam such as
whipped cream.
[0003] It is important to avoid accidental actuation of the trigger
causing an unintentional release of product, before the first use
as well as afterwards.
[0004] Document WO 2007/008375 A2 describes a diffuser according to
the preamble. This diffuser is composed essentially of a base
screwed on the vial, a push button provided with means for
actuating the valve and an outlet channel, a locking sleeve mounted
pivotable around the base and the push button, a housing
surrounding the base and the locking sleeve and on which a trigger
is articulated. A rib is secured to the inner face of the trigger.
The upper edge of the locking sleeve has two opposite vertices
separated by two recesses. The rib of the trigger and the vertices
of the sleeve are dimensioned so that when the vertices are located
under the trigger, the lower edge of the rib abuts on the edge of
the vertex located on the pivot side of the trigger. The latter
cannot be pushed down and it cannot depress the push button. If the
locking sleeve is rotated by a quarter turn, the recesses are now
located under the trigger. If pressure is exerted on the free arm
of the trigger, the latter pivots and moves down so as to press on
the push button. The rib no longer abuts on the upper edge of the
sleeve. This diffuser has several drawbacks. Firstly, it uses five
separate pieces. Moreover, since the locking means are located on
the pivot side of the trigger, it is necessary for the trigger to
have sufficient thickness not to bend under the effect of pressure
exerted on the free portion while the device is locked. If the
thickness is insufficient, it will be possible to operate the push
button even though the device is locked. This over-thickness of the
trigger contributes to increasing manufacturing costs. In addition,
to ensure locking, it is necessary for the edge of the rib to abut
on the edge of the locking sleeve. Thus, the rib exerts a
downwardly-oriented force parallel to the wall of the sleeve. A
slight deformation of one or another of the pieces can result in
that the required alignment is no longer ensured. The locking means
would then become ineffective.
[0005] Document EP 2 060 507 A2 discloses a diffuser consisting of
a base portion, a trigger articulated on the base, a push button
articulated on the trigger and provided with means for actuating
the valve and an outlet channel, blocking means being articulated
on the base. These blocking means pivot about a vertical axis that
is off-center relative to the diffuser as a whole. They include a
vertical wall in a circular arc which can be selectively, either
placed under the means for actuating the push button and thus block
the downward movement or, on the contrary, moved away from them so
that the actuation means can pass in front of the vertical wall and
move down to actuate the valve. The trigger is thus blocked
indirectly, via the push button which is articulated thereon. If
too much pressure is exerted on the trigger, there is a risk that
the flexible bridges connecting the push button to the trigger may
yield, resulting in the destruction of the diffuser. In addition,
since the locking means are connected to the base only by the pivot
axis, they are at risk of shifting to an undesired position with
the smallest jolt.
[0006] Document WO 98/32677 A1 discloses a trigger diffuser. It is
provided with a base in the form of a gun, a trigger articulated on
the base and intended to press on the push button of the vial on
which the diffuser is mounted, a plate pivotable about a horizontal
axis. The plate is provided with a slot into which the free end of
the trigger can penetrate when the plate is lowered. In this case,
the trigger cannot rotate and it cannot actuate the push button. If
the plate is raised, the end of the trigger no longer cooperates
with the slot of the plate. It is then possible to actuate the
trigger. This device, which is already cumbersome by design,
requires pulling out a plate in order to unlock the trigger.
[0007] The objective of the invention is therefore to provide a
diffuser according to the preamble which is both compact and easier
to carry. Another objective is to obtain a diffuser whose parts do
not require a large amount of material. A third objective is to
develop the blocking means so that they do not require high
precision positioning and/or manufacturing.
[0008] This objective is achieved according to the invention in
that, in the release position, the vertical wall is not aligned
with the rib of the trigger, and in the blocking position, the wall
is aligned with the rib of the trigger so as to block the movement
of the latter toward the diffusion position. Thus, depending on the
position of the wall with respect to the rib, it is possible to
block or not block the movement of the trigger.
[0009] To avoid over-dimensioning the trigger in order to prevent
it from being deformed if excessive pressure is exerted thereon
while the wall is in the blocking position, it is preferable to
secure the trigger to the diffuser by articulation means and to
arrange the rib of the trigger opposite from the articulation means
relative to the actuation means for actuating the valve.
[0010] To simplify the diffuser, the rib is preferably arranged on
the trigger so that it bears on one of the two faces of the
vertical wall so as to exert a force substantially orthogonal to
the vertical wall when the wall is in the blocking position and the
trigger is actuated. Even in the case of a deformation of the wall
or of the rib, the blocking function continues to be ensured
because the rib does not bear on the upper edge of the wall as in
the state of the art, but on its main surface.
[0011] In practice, the diffuser can be constituted by a base
provided with the fastening means, the actuation means and the
outlet channel, and on which the trigger is articulated. This makes
it possible to reduce the number of parts required for
manufacturing the diffuser.
[0012] Preferably, the trigger has substantially the shape of an
upside down L constituted by a first arm, called articulated arm,
whose end is provided with articulation means for articulating it
on the base, and a second branch, called free arm. In this case, it
is possible to place the rib on the face of the free arm oriented
toward the center of the diffuser.
[0013] Preferably, the vertical wall is secured to a pivoting
shield. This shield is placed inside the base and it is provided
with at least one lug projecting through a slot in a circular arc
formed in the base so that the lug or lugs are accessible from
outside the base. It is thus possible for the user to pivot the
shield, and with it, the vertical wall, by moving the lug or lugs
in their respective slots. Unlike in the state of the art, the
vertical wall in this case is located within the base, protected
from external shocks.
[0014] To retain the shield within the base, it is preferable to
provide at least one hook on the inside face of the base and at
least one slot in a circular arc in the shield, the hook or hooks
projecting into the slot or slots so as to hold the shield. The
shield is held vertically by the hooks, without being blocked in
rotation.
[0015] To avoid a deformation of the shield if excessive pressure
is exerted on the vertical wall orthogonally thereto, it is
possible to provide reinforcements on the shield, preferably on its
lower face.
[0016] In a preferred embodiment of the invention, the trigger is
secured to the base by a pivot. In addition, means may be provided
to prevent the trigger from rising beyond the neutral position.
[0017] The invention is explained in more detail with reference to
the following figures:

base according to FIG. 10.
[0029] For clarity, the description uses spatial references such as
"lower" and "upper." It should be noted that the diffuser is
manufactured and sold independently of the vial and that the
protection covers in particular the diffuser alone, without a vial.
Therefore, these references are made with respect to the diffuser
as it is intended to be used, assembled with a vial whose diffuser
is placed above the vial. This does not prevent the diffuser from
being used in an inverted position, that is to say, with the
diffuser under the vial, or in any other position.
[0030] The diffuser (1, 1') of the invention is essentially
constituted by a base (100, 100'), a trigger (200, 200')
articulated on the base (100, 100') by articulation means, and a
shield (300, 300') located inside the base (100, 100'). It is
designed to snap onto the neck of a vial (2) provided with a valve
(31), while remaining movable in rotation.
[0031] In the embodiments presented herein, the vial (2) is a
housing having a pointed-dome-shaped neck. It is closed by a cup
(3) provided with a valve (31) of the male type. The content of the
vial is pressurized. When the valve (31) is depressed, it opens and
the product is released. Of course, the valve can be a valve of the
female type, the actuation means being modified accordingly.
Similarly, the invention is not limited to pressurized vials. The
valve can be a valve closing a piston pump, for example.
[0032] The base (100, 100') has a circular skirt (101) designed to
snap onto the neck of the vial (2). Hereinafter, the axis of
rotational symmetry of the skirt is referred to as the axis of
symmetry. To this effect, the skirt (101) is provided with
fastening means (102) placed on its inner face and made in the form
of two ridges. The distance separating these two ridges corresponds
to the thickness of the mounting seam of the cup (3) set on the
vial neck (2). Thus, once snapped on this setting seam, the
diffuser cannot move vertically.
[0033] Above the skirt, the wall of the base is extended by two
shoulders (103) which are symmetrical so that the cross-section of
the base above these shoulders approaches the shape of a rectangle
with its two small sides in circular arcs. In one of these small
sides (104), a U-shaped aperture (105), open at the top, has been
formed. In the vicinity of the other small side (106), in the
extension of each longitudinal side, two flanges (107) have been
placed, which are parallel to the radial plane and between which a
horizontal pivot (108) perpendicular to the flanges (107) is
located.
[0034] The base (100, 100') is extended on the side of the flanges
(107) by a substantially horizontal wall from which a tongue (109)
extends. The outlet channel (110a, 110b) for the product coming
from the valve (31) is located on the lower face of this tongue
(109). This channel is divided into a vertical section (110b) which
is aligned with the axis of symmetry and ends at the bottom with
the actuation means (111) for cooperating with the valve (31), and
a section (110a) which is closer to the horizontal, opens to the
outside, and ends with a nozzle if appropriate. A guide groove
(112) is formed on the upper face of the tongue (109). This tongue
is sufficiently flexible so that it is possible to press it so as
to cause a downward movement of the outlet channel (110a, 110b) and
the actuation means (111).
[0035] On each shoulder (103), a slot (113) in a circular arc has
been provided, the center of the circle being located on the axis
of symmetry. In the vicinity of each slot (113), a hook (114) has
been placed on the inside face. These hooks are designed to hold
the shield (300, 300').
[0036] On the inner side of the base, reinforcing ribs (115) are
arranged at the base of the shoulders (103).
[0037] The trigger (200, 200') has substantially the shape of an
upside-down L constituted by a first arm, called articulated arm,
and a second arm, called free arm. At the end of the articulated
arm opposite the free arm, two hooks (201) have been placed on the
inner face for latching onto the pivot axis (108) of the base (100,
100'). Thanks to the lateral sides of the trigger, it is possible
to hide the pivot and the hooks. These hooks (201) and the pivot
axis (108) form articulation means. On the same face, closer to the
free arm, a guide rib (202) has been placed. This rib is positioned
such that, when pressure is exerted on the free arm in the
direction of the vial, the articulated arm comes to press on the
tongue (109) and the guide rib (202) penetrates into the guide
groove (112) of the tongue.
[0038] In the vicinity of the intersection between the two arms, an
opening (203) has been provided on the free arm. This opening is
dimensioned and positioned such that it is aligned with the outlet
end of the channel (110a). Thus, then the valve is actuated, the
product exiting the channel (110a, 110b) passes through this
opening (203). It is possible to expel the product, not in a jet
inclined with respect to the vertical, but in a jet along the axis
of symmetry. To this effect, the outlet channel can be limited to
its vertical portion (110a), and the opening (203) can be moved
onto the articulated arm.
[0039] On the inner side of the free arm, a second rib (204) has
been placed. This rib is positioned such that it penetrates without
difficulty into the U-shaped opening (105) of the base when
pressure is exerted on the free arm of the trigger (200, 200').
This rib (204) is parallel to the radial plane but does not pass
through the axis of symmetry. The cross-sectional views of FIGS. 3a
and 3b pass through this rib (204), which is offset relative to the
channel (110a, 110b), for example.
[0040] Inside the base (100, 100'), a shield (300, 300') is
provided to hold the means for blocking the trigger (200, 200').
This shield (300, 300') has substantially the shape of a circular
dome. It is provided with a central opening (301) to let the
vertical section (110b) of the channel and the actuation means
(111) pass through. It is also provided with two slots (302) in
circular arcs. These slots are dimensioned and positioned such that
the hooks (114) of the base can penetrate and remain stuck
therein.
[0041] The shield carries on its upper side two lugs (303) which
are dimensioned and arranged such that they penetrate into the
slots (113) in circular arcs of the base and project toward the
outside face of the base. These lugs (303) allow the user to pivot
the shield between two end positions limited by the abutment of the
lugs (303) on the ends of the slots (113) and/or of the hooks (114)
on the ends of the slots (302).
[0042] Further, the shield (300, 300') carries on its upper face a
substantially vertical wall (304) located in the extension of the
periphery of the shield. This wall constitutes the means for
blocking the trigger. It is supported by one or more radial
reinforcements (305). In the example shown, the vertical wall (304)
has a curved shape in the extension of the circumference of the
shield. It could also be made planar. This wall pivots between two
end positions at the same time as the shield. Like the shield, the
wall is located inside the base, protected from external shocks. In
a first position, called blocking position, the wall comes to close
the U-shaped opening (105) of the base. In the other end position,
called release position, the wall has pivoted sufficiently to free
the U-shaped opening (105).
[0043] Four recesses (306) are formed on the periphery of the
shield to allow the shield to pass through in the area of the
reinforcements (115).
[0044] The principle of operation of the diffuser of the invention
is described below in reference to FIGS. 2 and 3. In FIGS. 2a and
3a, the shield (300) is rotated in the blocking position. The lugs
(303) abut on the right end of the slots (113) of the base. The
wall (304) obstructs the opening (105) of the base. The trigger
(200) cannot be depressed, being blocked by the rib (204) which
comes to abut on the wall (304) while the articulated arm of the
trigger (200) does not press (or does not sufficiently press) on
the tongue (109) to cause the valve (31) to open. It is observed
that the rib (204) comes to abut against the outer vertical face of
the vertical wall (304) while exerting a force substantially
horizontal and directed toward the inside of the diffuser. This
force is thus substantially orthogonal to the vertical wall. The
wall is sufficiently wide so that it is not necessary to provide a
very accurate adjustment of the position of the rib (204) relative
to the U-shaped opening (105).
[0045] If the user rotates the shield (300, 300') by moving the
lugs (303) that protrude from the slots (113) toward the left,
until they come to abut against the other end of the slots (113),
the wall (304) pivots sufficiently to free the U-shaped opening
(105). The rib (204) can now enter this opening (105) and the
trigger can pivot sufficiently about the pivot (108) for the
articulated arm to come and press on the tongue (109) so as to push
it down in the direction of the valve. The actuation means (111)
then come into contact with the valve (31) and depress it, causing
it to open. When the pressure exerted on the free arm of the
trigger stops, the valve (31) pushes the actuation means back up,
and with them, the channel and the tongue (109). This in turn
pushes the articulated arm of the trigger back up, thus moving the
free arm away. The rib (204) comes back out of the slot (105) and
the shield (300, 300') can be moved back into the blocking position
if necessary.
[0046] It should be noted that in the view 3b, the tongue (109)
with the channel (110a, 110b) and the actuation means (111) are
shown incorrectly in the non-depressed position (as shown in FIG.
3a). In fact, the arm that connects the tongue (109) to the rest of
the body of the base is flexible enough to allow for the tongue to
be depressed.
[0047] In an alternative embodiment shown in FIGS. 7-11, some
improvements have been made to the basic model. Each improvement is
independent of the other, so it is not required to retain all of
them.
[0048] Additional reinforcements (307) have been provided under the
shield (300'). These reinforcements are in the form of two vertical
ribs, one of which is placed under the vertical wall (304) and the
other opposite therefrom. These ribs are dimensioned such that when
the diffuser (1') is placed on a container (2), they come to bear
on the cup (3). Thus, even if very high pressure is exerted by the
rib (204) on the vertical wall (304), the latter cannot yield by
pivoting backward and by deforming the shield downward.
[0049] Similarly, three reinforcements (305) have been provided
behind the vertical wall (304), thus allowing the rib (204) to bear
on the entire surface of the vertical wall without deformation of
the latter.
[0050] In order to prevent the trigger (200') from rising beyond
the neutral position, retaining means have been provided. These
retaining means are constituted by, on the one hand, a hook (205)
disposed on the lower face of the articulated arm, in the vicinity
of the articulation means. A corresponding slot (116) has been
formed in the tongue (109) of the base. After assembly of the
trigger on the base, the trigger is pushed down toward the base and
the hook (205) passes through the slot (116). If pressure is
exerted on the free arm of the trigger, the hook (205) moves down
within the base without interfering with the pivotal movement of
the trigger. Conversely, if the user tries to raise the trigger,
the trigger is retained by the hook which comes to abut against the
edge of the slot (116). Unless by forcing the hook until it is
destroyed, in principle, the user does not have access to the valve
(31) and does not risk soiling it.
[0051] Thanks to the rib being located, not on the articulated arm,
but on the free arm, it is possible to block the movement of the
trigger by having the rib abut, not on the upper edge of the wall,
but on its vertical face. Thus, cooperation between the rib (204)
and the wall (304) is guaranteed even in the event of a deformation
of one or another of the pieces. Moreover, an exact fit of the
pieces relative to one another is not required, unlike with the
blocking means proposed by the state of the art.
[0052] In addition, by placing the blocking means opposite from the
pivot (108) relative to the contact point between the trigger and
the tongue (109) carrying the actuation means (111), it is not
necessary to over-dimension the trigger. Indeed, even if excessive
pressure is exerted on the free arm while the vertical wall is
aligned with the rib, the trigger will not be deformed as it bears
on one side on the pivot (108) and on the other side on the
vertical wall.
[0053] Rather than a pivot axis, it is also possible to secure the
trigger to the base by a film hinge. To this effect, the base and
the hinge can be manufactured by injection in one piece, for
example. The hinge can also be overmolded on a previously
injection-molded base, or vice versa. The film hinge performs the
function of articulation means.
